Sunrise personality Samantha Armytage has been replaced as the host of a fundraising lunch honouring refugee women with US actress and UNHCR ambassador Kristin Davis, a day after the pair participated in an awkward Sex and the City skit on Channel Seven's breakfast television show.

Armytage was due to MC the $200-a-head lunch, organised for Australia for UNHCR, which kicked off at midday on Friday in The Ivy Ballroom in Sydney. During the event, Armytage was due to hold a question-and-answer session with Davis about her work with refugee women.

But Armytage and her co-host David Koch revealed on Sunrise on Friday morning that Armytage would no longer attend the event.

The change comes a day after Davis appeared on Sunrise and was asked to reprise her role as her Sex and the City character Charlotte York in a bizarre skit.

"You guys have seriously lost your mind," Davis said as Armytage, taking on the role of Carrie, pulled on a blonde curly wig. The duo were joined by fellow Sunrise stars Edwina Bartholomew, as Samantha, and Natalie Barr in a red wig as Miranda.

"Sarah Jessica [Parker, the original Carrie Bradshaw] is not going to be happy about this," Davis said.

The scene focused on Carrie being broken up with by Post-It note.

Later, Davis retweeted a fan who wrote: "That was the worst piece of TV I've ever seen. Kristin, you and your charity work is great. Shame Sunrise."

Davis also sent a wink emoji to rival Today breakfast host Lisa Wilkinson, after the Channel Nine personality tweeted the star.
